Pipes are made by ERW process.

The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding to a minimum of 1000°F(540℃)so that no untempered martensite remains, or otherwise processed in such a manner that no untempered martensite remains.



Diameter-- For pipe NPS1 1/2 (DN40) or smaller, the outside diameter at any point shall not vary more than ± 1/64in (0.4mm) from the specified outside diameter. For pipe NPS2 (DN50) or larger, the outside diameter shall not vary more than ±1% from the specified outside diameter.


Thickness—The minimum wall thickness at any point shall be not more than 12.5% under the specified wall thickness.


Weight(Mass):-- The weight(mass) of the pipe shall not vary more than ±10% from its specified weight(mass), as derived by multiplying its measured length by its specified weight(mass) per unit length.


Workmanship, Finish, and Appeaerance:

The pipe manufacturer shall explore a sufficient number of visual surface imperfections to provide reasonable assurance that they have been properly evaluated with respect to depth.


Test and Inspection:

- Mechanical Test

- Tension Test

- Flattening Test

- Hardness Test

- Bend Test

- Hydrostatic Test

- Nondestructive Electric Test
